Benefits of technology

[0006]In view of the foregoing, an object of the present invention is to provide a cosmetic composition which can contain such a skin-revitalizing agent at a high concentration, thereby attaining an improved skin-revitalizing effect.
[0009]According to the present invention, since a skin-revitalizing agent can be incorporated into a cosmetic composition at a high concentration, a further improved skin-revitalizing effect of the composition can be obtained.

Problems solved by technology

However, such a skin-revitalizing agent is difficult to dissolve in water, and thus can only be incorporated into a currently employed cosmetic product in an amount of up to 1 wt.
Therefore, a cosmetic product containing such a skin-revitalizing agent fails to satisfactorily exhibit the effect of the agent.

examples

[0016]The present invention will next be described by way of examples, which should not be construed as limiting the invention thereto.

[0017]Each of the skin-revitalizing agents shown in Table 1 was incorporated into purified water in an amount (wt. %) shown therein. In the Comparative Examples, each of the skin-revitalizing agents shown in Table 1 was added to purified water in an amount shown therein, followed by stirring at 50° C. for 30 minutes and then cooling to 20° C. Immediately thereafter, the state of dissolution was observed (shown in the column “Immediately after dissolution” of Table 1). Subsequently, the sample was stored at 5° C. for 24 hours, and the state of dissolution was also observed (shown in the column “After storage” of Table 1).

[0018]In the Examples, each of the skin-revitalizing agents shown in Table 1 was added to purified water in an amount shown therein, followed by stirring at 50° C. for 30 minutes. The resultant aqueous dispersion was subjected to a na...

Abstract

The invention provides a skin-revitalizing cosmetic composition for alleviating or eliminating skin problems such as dry skin, wrinkles, and age spots, the composition containing a skin-revitalizing agent at high concentration. The skin-revitalizing cosmetic composition contains a skin-revitalizing agent selected from the group consisting of aloe extract, placenta extract, hydrolyzed elastin, hydrolyzed collagen, and sodium hyaluronate, wherein the skin-revitalizing agent is in the form of nanoparticles obtained through a nanoparticle-forming treatment.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a cosmetic composition, and more particularly to a skin-revitalizing cosmetic composition for alleviating or eliminating skin problems such as dry skin, wrinkles, and age spots.[0003]2. Background Art[0004]There have been well known cosmetic products containing a skin-revitalizing agent for alleviating or eliminating skin problems such as dry skin, wrinkles, and age spots. For example, Japanese Patent Application Laid-Open (kokai) No. 2005-53842 discloses a cosmetic product containing an aloe extract; Japanese Patent Application Laid-Open (kokai) No. 2001-72567 discloses a cosmetic product containing a placenta extract; Japanese Patent Application Laid-Open (kokai) No. 2006-131557 discloses a cosmetic product containing hydrolyzed elastin; Japanese Patent Application Laid-Open (kokai) No. 2003-300854 discloses a cosmetic product containing hydrolyzed collagen; and Japanese Patent Applica...
